Frontotemporal Lobar Degeneration

Open publisher page 1 citations

Abstract

Frontotemporal dementia (FTD) is an uncommon but important form of degenerative disease characterized by clinical syndromes that result from degeneration of the frontal and temporal lobes. FTD is divided based on clinical presentation into behavioral variant FTD (bvFTD), semantic dementia, and progressive nonfluent/agrammatic aphasia. Several recent studies have advanced our knowledge of the genetics of FTD, with the three most common FTD genes being microtubule-associated protein tau (MAPT) and progranulin (GRN), and a noncoding repeat expansion in C9ORF72. Tau and TDP-43 are the most common pathologies associated with FTD. No pharmacological therapies are currently approved for use in FTD.
